@nodebraid/canvas-fragment

Package is not publicly released

This name describes the current source module boundary; it is not an npm installation claim.

A Canvas Fragment is an immutable, canonically ordered selected-Node induced subgraph: every selected Node, the complete Edge closure between those Nodes, and explicit Edge members from the original Selection. It preserves nested parents, port-qualified Endpoints, self-loops, parallel Edges, and opaque data references.

The public interface contains only captureCanvasFragment(), acceptCanvasFragment(), materializeCanvasFragment(), value types, and structured errors. The package does not depend on Runtime, Renderer, React, browsers, or Cordis.

A Canvas Fragment is not a Serialized Document. It defines no persistence schema version, text envelope, deep clone, generic JSON codec, or cross-version compatibility promise. Applications own concrete text representations.
